· Answer the following questions about the information in Appendix J:
o What bequeath be printed if the input is 0?
o What lead be printed if the input is 100?
o What will be printed if the input is 51?
o What will be printed if the user enters Wingding?
o Is this design robust? If so, pardon why. If not, explain what you hatful do to make it robust.
o How many levels of nesting are there in this design?
o Provide a coterie of values that will screen out the normal operation of this political platform segment.
Defend your choices.
o Provide a set of runnel values that will cause each of the branches to be executed.
o Provide a set of test values that test the abnormal operation of this program segment. 

Consider the following survival of the fittest statement where X is an integer test score amid 0 and 100.

input X

if (0 <= X and X < 49)
output you crumble

else if (50 <= X and X < 70)
output your grade is X
output you did OK

else if (70 <= X and X < 85)
output your grade is X
output you did tumefy

else if (85 <= X and X < 100)
output your grade is X
output you did dandy

endif
output how did you do?

 
What will be printed if the input is 0?
 
You fail.
How did you do?




 
  What will be printed if the input is 100?
 
How did you do?
 
   What will be printed if the input is 51?
 
Your grade is 51.
You did OK.
How did you do?
 
What will be printed if the user enters Wingding?
 
The program will abnormally terminate because it is expecting an integer value, and a string value will cause the program to crash.
 
   Is this design robust? If so, explain why. If not, explain what you can do to make it robust.
 
No, there is no thoughtlessness condition for Scores >= 100, or scores < 0. In addition, 49 and 100 are valid scores. The following should, therefore, be added:
 
if (0 <= X and X <= 49)
output you...If you want to get a just essay, order it on our website: Ordercustompaper.com
